      <p>这个星期去杭州参观学习了一圈，参观了两家主要是做硬件的厂商，一共参观了两间公司，虽然我还只是一个入行一年的菜鸟，但是有些感想还是想要写下来。</p>

<h2 id="机器学习">机器学习</h2>

<p>第一间公司的名字中带VISION，从名字久可以看出，这是一家主攻视频的公司，参观过程中给我印象最深刻的就是将机器学习做成了各种产品。
比如说，视频中的人物特征识别，就是通过大量的样本训练+输出分类标识，训练出算法之后，在摄像头实时将捕捉到的画面作为输入参数，再在经过算法计算后以阈值作为判断给出结果。
从结果来看，光是人的各种穿着特征就需要非常多的标签，标记就需要非常多的工作量，更不用说将样本的每一个细节都做标记。
在这间公司的饭堂过道可以看到一些摄像头，我估计是用来做样本采集或是测试的，估计幕后就有工作人员为样本做标签了吧。</p>

<h2 id="产品经理">产品经理</h2>

<p>除开技术，能够将机器学习应用到实际需求当中来也是令人印象深刻。在之前看机器学习的时候，还只是将期作为简单的数据分析工具，虽然有讲过机器学习在自动驾驶方向的应用，但是没想到实际还可以应用到这么细的领域。</p>

<h2 id="工程控制">工程控制</h2>

<p>两间公司都有适合自己的开发流程，并且有非常完善的基础建设（版本、测试等等），这写我现在的公司是没办法比的，当然，有些东西我也没有去帮忙建设，这个也有执行力度方面的问题吧。</p>

<h2 id="总结">总结</h2>

<p>虽然一些大公司的做法在网上也有所耳闻，但是还是要自己去看去感受才知道这样的做法带来的好处（虽然老板是看不到这些细节的）。</p>
